A small study of elite ballet dancers has concluded that supplementing with Vitamin D3 has beneficial effects on muscular performance and injury occurrence.
Although this study was carried out during the winter months when the participants had low exposure to sunlight, it indicates that adequate levels of Vitamin D3 are important.
The controlled study gave the ballet dancers a 4-month oral supplementation of vitamin D3 (2000IU per day). Isometric muscular strength (static strength training as opposed to dynamic movement) and vertical jump height were measured pre and post intervention.
Significant increases were noted for the group taking the supplementation for isometric strength and vertical jump. They also sustained significantly less injuries than the controls during the study period.
My advice is to ensure adequate levels of Vitamin D through safe sun exposure during the summer months: click on the link below to read my previous blog on this subject.
It may also be worth getting your Vitamin D levels checked during the winter (traditionally levels are likely to be at their lowest in January/February) to make sure you are not low in this important vitamin.
